Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615784, here are decompositions:

13 + 8615771 = 8615784
17 + 8615767 = 8615784
61 + 8615723 = 8615784
127 + 8615657 = 8615784
131 + 8615653 = 8615784
193 + 8615591 = 8615784
197 + 8615587 = 8615784
241 + 8615543 = 8615784

Showing the first eight; more decompositions exist.
